...To obtain a powder diffraction pattern, calculations are carried out in three-dimensional reciprocal space along rods passing through the nodes of the reciprocal two-dimensional lattice. The program allows one to determine the type and estimate the concentration of planar defects of the studied sample particles by creating a model of a 1D disordered crystal and optimizing it by trial and error until the best match with the experiment.

Object-oriented crystallographic library and program, for the analysis of Crystal structures from scattering experiments: optimized scattering computation, Graphical interface for structures and data, global optimization algorithms.

QXRD is software for the acquisition and analysis of X-ray data taken with 2 dimensional detectors. The software can drive a Perkin Elmer XRD series flat panel detector and can be remote-controlled via a socket interface, or directly from SPEC

SW for indexing of powder diffraction data. It is written to be multiplatform. The computation can be done with multiple threads or sometimes with CUDA support. For detailed information see wiki page.

DiPoly is a new software that implements basic diffraction methods for the structural characterization of biopolymers. It is freeware with a friendly interface for the analysis of experimental powder X-ray diffractograms of polymer samples of biomass of various origins. A complex approach approach based on a combination of the Segal, decomposition and LeBale methods is used to estimate the degree of crystallinity.

Scanning and tomographic X-ray Powder Diffraction data processing.

...The program allows you to quickly create, modify and analyze complex models of nanostructures. The software is now integrated into program DiAnNa (https://sourceforge.net/projects/dianna) for calculating powder X-ray diffraction.

Crystalsim is a simple freeware program with a neat graphical user interface for X-ray diffraction (XRD) data analysis . It can simulates all possible {hkl} planes data for the selected crystal. Crystallographic Information File (.cif) can also be used. Analyze both powder diffraction and single crystal data . Indexed at International Union of Crystallography (IUCR). Crystalline lattice parameters such as ‘a’, ‘b’, ‘c’ as well as interfacial angles such as alpha, beta, gamma can also be entered manually. ...

A Suite of Programs implementing a fast approach to the Debye Function Analysis (DFA) of powder diffraction data from nanocrystalline and/or non-ordered materials. See J. Appl. Cryst. 2015, 48, 2026-2032

xylib is a portable library for reading x-y data from powder diffraction, spectroscopy and other experimental methods. Supported formats: VAMAS, pdCIF, Bruker, Philips, Rigaku DAT, Sietronics CPI, DBWS/DMPLOT, Koalariet XDD and others.

DDM program is designed for crystal structure analysis from powder diffraction data by making use of either Rietveld or Derivative Difference Minimization (DDM) method. In the DDM method the refinement is aimed not at minimizing the absolute difference between the experimental and calculated profiles but at minimizing the oscillations (or curvature) of the difference curve. The squared values of the difference curve derivatives are used in DDM as a measure of the difference curvature. ...

Library for manipulating and exchanging powder diffraction data files in various formats.

XDiff is a program for numerical calculations of X-ray powder diffraction patterns of nanocrystals dispersed in a liquid phase
